Panzer Dragoon series

I saw a topic in the HDIJ sub forum which got me wondering, how many of you got the chance to play the classic that is the panzer dragoon series? Some of the games are quite rare (the 3rd one can go up to £200 on ebay) and they were on the saturn (apart from Orta which is on the X-box), which mainly means it has a kick ass OST. I myself have only played 3 of the 4 games, which are the first 2 and the one on the X-box. So have you lot heard of it and if you have played it do you wish sega would make a new one?

I've played everyone except Saga. They are amazing games with a unique atmosphere. I really don't want Sega to try another game because of the high possibility of them messing it up.

I own Zwei, Orta (and by connection, the original), and as of yesterday, Saga. The shooters are okay, but perhaps a little too hard for their own good. The RPG, for the two hours I've played it thus far, is quite orgasmic.
